AUTOMOBILE RADIATOR CAP.

Application filed November 19, 1 924, Serial No. y750,820;

This invention relates to automobile radiator caps, and has particular reference to radiator caps of the non-removabletype.

It has been proposed heretofore to provide non-removable radiator caps adapted tov be permanently screwed into the nipple of the radiator opening of an automobile so as to prevent any unauthorized removal thereof, and which are constructed to permit the filling of the radiator in a well known manner. The chief disadvantage in the use of a radiator cap of the type referred to lies in the fact that it is necessary for the retail dealer to keep in stock a large number` thereof of varying diameters in order tolit the dierent makes of automobiles, each of which is provided with a diiferent size thread* and filling opening for the radiator.

A general object of the present invention resides in the provision of a non-removable radiator cap which can befapplied with equal facility to any type of radiator.

A further object of the invention resides in a non-removable radiator cap in which the ordinary radiator cap withwhich all automobiles are furnished is utilized, thereby preventing the scrapping of the latter as necessary in rthe application of caps of this type heretofore in use.

A further feature of the invention consist-s in a novel non-removableradiator cap which is simple in construction, readily applicable to any make of automobile,'durable iii use, and comparatively cheap to manufacture. l y

These and other important features of this invention will appear'from the following detailed description read in connection with lthe accompanying drawings, and' will be particularly pointed out inthe appended claims. t

In the drawings; Figure l is a side elevation of-a preferred form of the invention;

Figure 2 is a rea-r elevation thereof;l Figure 3 is a vertical section of the casing,

the position assumed by the top in open posi-y tion being shown invdotted lines; and

Figure i is a frontelevation of the body Yof the casing.

Referring more particularly to the drawings, the usual radiator V cap for'closing the filling opening of an automobile radiator is indicated at 2. The cap 2 is ordinarily provided with .an opening 4: adapted to receive a temperature indicator, mascot, or similar device therein. The construction of the cap is welly known, and, since it does not constitute an essential part of the present inyention, will not be described in detail vherein;

The reference character 6 designates a hol-l low cylindrical body or casing comprising a Wall portion 8 and a bottom l0. The under side of the bottom is slightly concave,y as illustrated in Figurey 3, to conform with the top of the radiator cap 2', upon which the casing is mounted. Y The bottoinlO ofthe casing is formed with a central opening 12 which communicates withr a centrally .arranged tube 14 formed -inte al' with the bottom of the casing. The tu e 14 is screwthreaded and adapted to extend through the opening tof the cap 2. A washerv 16 and lock nut 18 serve to securely retain the casing upon' the cap 2 in a manner clearly understood. Y

The casing 6' is provided with a rearwardly and upwardly extending lug 20 ywhich is bifurcated at its upper end to provide spaced bearing arms 22 for a purpose hereinafter described. -The casing V6Y is provided with a cover or top 24 having a peripheral flange 26 adapted to snugly fit-around'the-gupper edge of the casing; 4The top 24 is provided with a gasket or washer 28 of rubber or other suitable material which serves to hermetically s eal the casing when the top is in closed position.

The top 24 is formed with an `integra-l lug 30 having an elongated slot 32 therein, the said lug being adapted to extend between the bearing arm 22 previously mentioned. A stud or bolt 33 extends through the arms 22 and the elongated .slot in the lugSO to afford a pivotal mounting for. the top. The lug 30 is also formed with an extension or tail 34 adapted to engage the side of the casing to limit the pivotal movementof the vtop when the latter is opened.

The top 24 is provided with an upstanding boss'36 adapted to support a temperature indicator, mascot, orsiniilar device 38. :The temperature indicator is of standard and well known construction, and need not be described in detail. As illustrated, the temperature indicator is provided with a pedestal 40 ,adaptedto seat upon the boss 36 andhas a reduced extension 42 extending through thefbo'ss, the top 24, and the rubber gasket 28, suitable holes being provided in thev top' and gasket for this purpose. A

cap, said tubular member forming a passage- Way between the casing and the radiator, a hinged top on said casing provided with an opening therein to receive a portion of a temperature indicator, mascot or similar device, means on the inside oi the top for securing the temperature indicator, mascot or similar device to the top of the casing, and releasable means for retaininnf the top of the casing in closed position. f

6. A filling device for automobile radiators adapted to be attached to the usual radiator cap which has been kpermanently fixed to the radiator neck, said filling device comprising a casing adapted to seat on the radiator cap, a tubular member formed upon the bottom of the casing adapted to extend through an opening in the radiator cap, said tubiilar member forming a passageway between the casing and the radiator, means on e;

the interior of the radiator cap engaging said tubular member for securing the casing to the cap, a hinged top on said casing adapted to carry a temperature indicator,

mascot or similar device, means for arresta
